feat: Retain the response and justification fields in VEX input

[cinix]

• Updated input_vex() to retain triage justification and response from a vex input file.
• Updated input_vex() to use the CycloneDX v1.4 state enumerations when mapping to the Remarks enum.
• Replaced Remarks.Ignored with False Positive and Not Affected to keep the same granularity with the CycloneDX analysis states.
• Fixed an issue where the metrics table may have duplicate rows when output to the console.
• Updated test vector inputs to validate against CycloneDX schema.
